Recent evidence demonstrates the benefits of integrated agriculture and nutrition programs for children's health and nutrition outcomes. These programs may also improve mothers' nutrition and empowerment outcomes. However, evidence from rigorous evaluations is scarce.
We examined impacts of Helen Keller International's 2-y enhanced-homestead food production (E-HFP) program in Burkina Faso on the secondary impact measures of mothers' nutrition and empowerment.
We used a cluster-randomized controlled trial whereby 55 villages with 1767 mothers of young children were randomly assigned to 3 groups: 1) control, 2) E-HFP with the behavior change communication (BCC) strategy implemented by older women leaders, or 3) E-HFP with BCC implemented by health committee members. Data for the treatment groups were pooled for this analysis because no differences were found between the 2 groups in key mothers' outcomes. We used difference-in-differences (DID) estimates to assess impacts on mothers' dietary intake, diversity, body mass index (BMI; in kg/m(2)), prevalence of underweight (BMI <18.5), and empowerment.
The E-HFP program significantly increased mothers' intake of fruit (DID = 15.8 percentage points; P = 0.02) and marginally increased their intake of meat/poultry (DID = 7.5 percentage points; P = 0.08) and dietary diversity (DID = 0.3 points; P = 0.08). The prevalence of underweight was significantly reduced among mothers in treatment compared with control villages by 8.7 percentage points (P < 0.01). Although the changes in BMI did not differ between mothers in treatment and control villages, there was a marginally significant interaction (baseline underweight × change in BMI; P-interaction = 0.07), indicating that underweight mothers had a greater increase in BMI than did mothers who were not underweight. The E-HFP program also positively affected mothers' overall empowerment score (DID = 3.13 points out of 37 possible points; P < 0.01) and 3 components of empowerment: meeting with women (DID = 1.21 points out of 5 possible points; P < 0.01), purchasing decisions (DID = 0.86 points out of 8 possible points; P = 0.01), and health care decisions (DID = 0.24 points out of 2 possible points; P = 0.05).
Helen Keller International's E-HFP program in Burkina Faso substantially improved mothers' nutrition and empowerment outcomes. These positive impacts benefit the mothers themselves and may also improve their ability to care for their children. This trial was registered at clinicaltrials.gov as NCT01825226.
近期证据表明,农业与营养综合项目对儿童健康和营养状况有益。这些项目还可能改善母亲的营养状况并增强其权能。然而,来自严格评估的证据很少。
我们考察了海伦·凯勒国际组织在布基纳法索实施的为期两年的强化家庭食物生产(E-HFP)项目对母亲营养和权能的次要影响指标。
我们采用了整群随机对照试验,将55个村庄的1767名幼儿母亲随机分为3组:1)对照组;2)由年长女性领袖实施行为改变沟通(BCC)策略的E-HFP组;3)由卫生委员会成员实施BCC的E-HFP组。由于两组在关键的母亲结局方面未发现差异,因此将治疗组的数据合并进行此分析。我们使用差分法(DID)估计来评估对母亲饮食摄入量、多样性、体重指数(BMI;单位:kg/m²)、体重不足患病率(BMI<18.5)和权能的影响。
E-HFP项目显著增加了母亲的水果摄入量(DID=15.8个百分点;P=0.02),并略微增加了她们的肉类/家禽摄入量(DID=7.5个百分点;P=0.08)和饮食多样性(DID=0.3分;P=0.08)。与对照村庄相比,治疗组母亲的体重不足患病率显著降低了8.7个百分点(P<0.01)。尽管治疗组和对照村庄母亲的BMI变化没有差异,但存在略微显著的交互作用(基线体重不足×BMI变化;P交互作用=0.07),表明体重不足的母亲BMI增加幅度大于非体重不足的母亲。E-HFP项目还对母亲的总体权能得分产生了积极影响(DID=3.13分,满分37分;P<0.01)以及权能的三个组成部分:与女性会面(DID=1.21分,满分5分;P<0.0
